An atom with incomplete octet tends to attain the noble gas configuration by the gain or loss of electrons. If an atom contains 2 electrons in its outer orbit, it would be more energy efficient for it to lose the two electrons and complete the octet, as opposed to gaining 6 electrons for the same.
With a covalent bond, atomic nuclei are sharing some of their valance electrons, which means that the electrons are in orbit around both (or all of) the nuclei in question. With an ionic bond, valance electrons are transferred from one atom to another. Once transferred, the electrons orbit only around the atomic nucleus that has received them.
Fe2O3. Iron three contains three electrons in the outer orbit and Oxygen has two slots empty in the outer orbit, so in order for the compound to combine, three oxygen atoms are needed for two Fe atoms, and then the compound is neutral.
for that you should have the knowledge of the electron configuration 2,8,8,18,32,.. meaning first electronic orbit can have at the most two electrons. second orbit can have only 8 electrons and so on.... Now, for example calcium atomic number is 20 . so how will be the electrons placed 2 will go in the first orbit, 8 will go in the second orbit - so till now total is 10 we still have 10 more electrons to arrange. 8 electrons go in the third orbit and last 2 electrons go in the fourth orbit which actually has the capacity to accept total of 18 - now 2 electrons come in the fourth orbit so 18-2=16 . for any element it requires a lot of energy to get 16 electrons from the atom of other element so it will be better to loose 2 electrons for the calcium atom. Ca +2 means it has 2 electrons to loose . try this with different element and if you have any problem I will help you
In the 1st orbit, there are 2 electrons and in the 2nd orbit are 5 electrons.
Two atoms who are looking to complete their outer orbit will share their electrons one losing electrons and becoming positive and one gaining Electrons becoming negative. Then the two are bonded together because opposites attract.
because of a ionic bond between the electron and the nucleus

The valence shell is the outer most shell or imaginary orbit of an atom containing <8 electrons. The electrons in this shell are called 'valence electrons'.

The second orbit has 8 electrons.
A shell surrounding the nucleus of an atom containing electrons.
13 electrons are in the third orbit of Manganese.
do electrons orbit the nucleus like plantes orbit the sun?
Two (2) electrons can be held in the first orbit.
There is surprisingly little in common between the orbit of an electron and the orbit of a planet. It is magnetism that holds an electron in position and gravity that holds a planet in its orbit. If the electrons orbit was similar to the earths it would be able to loose energy at a constant rate and would crash into the proton. The electron can only loose energy in quantized amounts and is only aloud a canonical ensemble of values.
